Widescreen mode cuts CG
Spoiler:
And the resolution of the monitor 1366x768 is too small. I have 1440x900 and can only fit with a window size of 0.80x
And with regards to the error under your first spoiler. I had this at the end of the prologue when the video opening started playing. The size of the game window has decreased. And after the end of the video has increased and the main menu of the game was compressed.
